Abstract: A contiguous deep trench includes a first trench portion having a constant width between a pair of first parallel sidewalls, second and third trench portions each having a greater width than the first trench portion and laterally connected to the first trench portion. A non-conformal deposition process is employed to form a conductive layer that has a tapered geometry within the contiguous deep trench portion such that the conductive layer is not present on bottom surfaces of the contiguous deep trench. A gap fill layer is formed to plug the space in the first trench portion. The conductive layer is patterned into two conductive plates each having a tapered vertical portion within the first trench portion. After removing remaining portions of the gap fill layer, a device is formed that has a small separation distance between the tapered vertical portions of the conductive plates.

Abstract: The present invention includes embodiments of a processing method, and resulting structure, for building a chip having a TSV pillar which can be used as an interconnecting structure. The process includes the deposition of a dual diffusion barrier between the TSV and the substrate the TSV is embedded within. The TSV is then exposed from the back side of the substrate so that at least a portion of the TSV protrudes from the substrate and can be used as a contact for connecting the chip to another surface. The resulting TSV is rigid, highly conductive, can be placed in a tightly pitched grid of contacts, and reduces effects of CTE mismatch.
